Haplogroup L2 (mtDNA)
Haplogroup L2 is a human mitochondrial DNA (mtDNA) haplogroup with a widespread modern distribution, particularly in Sub equatorial Africa. Its L2a subclade is a somewhat frequent and widely distributed mtDNA cluster on the continent, as well as among African Americans, The highest frequency occurs among the Mbuti Pygmies (64%). Origin L2 is a common lineage in Africa. It is believed to have evolved between 87,000 and 107,000 years ago or approx. 90,000 YBP. Its age and widespread distribution and diversity across the continent makes its exact origin point within Africa difficult to trace with any confidence. L2 Haplotypes is commonly observed in Central & South Eastern African populations, finding shared genetic matches with Southeast Africa and Central Africa. An origin for L2b, L2c, L2d and L2e in Southeastern Africa seems likely. The early diversity of L2 can be observed all over the African Continent, but as we can see in Subclades section below, the highest diversity is f ...

Human Mitochondrial DNA Haplogroup
In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe. The letter names of the haplogroups (not just mitochondrial DNA haplogroups) run from A to Z. As haplogroups were named in the order of their discovery, the alphabetical ordering does not have any meaning in terms of actual genetic relationships. The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans. She is commonly called Mitochondrial Eve. The rate at which mitochondrial DNA mutates is known as the mitoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Africa
Central Africa is a subregion of the African continent comprising various countries according to different definitions. Angola, Burundi, the Central African Republic, Chad, the Democratic Republic of the Congo, the Republic of the Congo, Equatorial Guinea, Gabon, Rwanda, and São Tomé and Príncipe are members of the Economic Community of Central African States (ECCAS). Six of those states (the Central African Republic, Chad, the Republic of the Congo, Equatorial Guinea, and Gabon) are also members of the Economic and Monetary Community of Central Africa (CEMAC) and share a common currency, the Central African CFA franc. The African Development Bank defines Central Africa as the Central African Republic, Chad, the Democratic Republic of the Congo, the Republic of the Congo, Equatorial Guinea, and Gabon. Middle Africa is an analogous term used by the United Nations in its geoscheme for Africa. It includes the same countries as the African Development Bank's defin ...

Tigrayans
Tigrayans ( ti, ተጋሩ) are a Semitic-speaking ethnic group indigenous to the Tigray Region of northern Ethiopia. They speak the Tigrinya language, an Afroasiatic language belonging to the Ethiopian Semitic branch. The daily life of Tigrayans is highly influenced by religious concepts. For example, the Christian Orthodox fasting periods are strictly observed, especially in Tigray; but also traditional local beliefs such as in spirits, are widespread. In Tigray the language of the church remains exclusively Ge’ez. Tigrayan society is marked by a strong ideal of communitarianism and, especially in the rural sphere, by egalitarian principles. This does not exclude an important role of gerontocratic rules and in some regions such as the wider Adwa area, formerly the prevalence of feudal lords, who, however, still had to respect the local land rights. History The majority of Tigrayans trace their origin to early Semitic-speaking peoples whose presence in the region dates b ...

Gurage
The Gurage (, Gurage: ጉራጌ) are a Semitic-speaking ethnic group inhabiting Ethiopia.G. W. E. Huntingford, "William A. Shack: The Gurage: a people of the ensete culture" They inhabit the Gurage Zone, a fertile, semi-mountainous region in central Ethiopia, about 125 kilometers southwest of Addis Ababa, bordering the Awash River in the north, the Gibe River, a tributary of the Omo River, to the southwest, and Hora-Dambal in the east. According to the 2007 Ethiopian national census the Gurage can also be found in large numbers in Addis Ababa, Oromia Region, Dire Dawa, Harari Region, Somali Region, Amhara Region, Gambela Region, Benishangul-Gumuz Region, and Tigray Region. History According to the historian Paul B. Henze, the Gurage origin is explained by traditions of a military expedition to the south during the last years of the Kingdom of Aksum, which left military colonies that eventually became isolated from both northern Ethiopia and each other.

Amhara People
Amharas ( am, አማራ, Āmara; gez, ዐምሐራ, ʾÄməḥära) are a Semitic-speaking ethnic group which is indigenous to Ethiopia, traditionally inhabiting parts of the northwest Highlands of Ethiopia, particularly inhabiting the Amhara Region. According to the 2007 national census, Amharas numbered 19,867,817 individuals, comprising 26.9% of Ethiopia's population, and they are mostly Oriental Orthodox Christian (members of the Ethiopian Orthodox Tewahedo Church). They are also found within the Ethiopian expatriate community, particularly in North America. They speak Amharic, an Afro-Asiatic language of the Semitic branch which serves as one of the five official languages of Ethiopia. As of 2018, Amharic has over 32 million native speakers and 25 million second language speakers. Various scholars have classified the Amharas and neighboring populations as Abyssinians.

Cushitic Languages
The Cushitic languages are a branch of the Afroasiatic language family. They are spoken primarily in the Horn of Africa, with minorities speaking Cushitic languages to the north in Egypt and the Sudan, and to the south in Kenya and Tanzania. As of 2012, the Cushitic languages with over one million speakers were Oromo, Somali, Beja, Afar, Hadiyya, Kambaata, Saho, and Sidama.

Nubia
Nubia () (Nobiin: Nobīn, ) is a region along the Nile river encompassing the area between the first cataract of the Nile (just south of Aswan in southern Egypt) and the confluence of the Blue and White Niles (in Khartoum in central Sudan), or more strictly, Al Dabbah. It was the seat of one of the earliest civilizations of ancient Africa, the Kerma culture, which lasted from around 2500 BC until its conquest by the New Kingdom of Egypt under Pharaoh Thutmose I around 1500 BC, whose heirs ruled most of Nubia for the next 400 years. Nubia was home to several empires, most prominently the Kingdom of Kush, which conquered Egypt in the eighth century BC during the reign of Piye and ruled the country as its 25th Dynasty (to be replaced a century later by the native Egyptian 26th Dynasty). From the 3rd century BC to 3rd century AD, northern Nubia would be invaded and annexed to Egypt, ruled by the Greeks and Romans. This territory would be known in the Greco-Roman world as Dodek ...

Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing drought, desertification, and a large drop in sea levels. Based on changes in position of ice sheet margins dated via terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets commenced 33,000 years ago and maximum coverage was between 26,500 years and 19–20,000 years ago, when deglaciation commenced in the Northern Hemisphere, causing an abrupt rise in sea level. Decline of the West Antarctica ice sheet occurred between 14,000 and 15,000 years ago, consistent with evidence for another abrupt rise in the sea level about 14,500 years ago. Glacier fluctuations around the Strait of Magellan suggest the peak in glacial surface area was constrained to betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
